Text email is universal. HTML email alienates a great many people. If I wanted to see HTML, I'd use a browser or an HTML editor.
Check out this survey, done in 2003: http://www.wilsonweb.com/wmt8/email_format_preferences.htm
87% of the non-technical survey group reported being able to read HTML email, and 93% of the business group. HTML was reported to be preferred over plain text by both groups.
